This paper is based upon material collected during my last 
visit to the islands in 1905—06. The specimens brought home 
have for the most part been dried but a good deal also have been 
preserved in spirit or formalin. 
At first it had been my intention to work out all my material 
of the Codiaceæ but as Mrs. and Mr. Gepp in London have in- 
formed me that they are working out a monograph of this family 
I have preferred to put off my examination of this group until 
their paper has appeared. 
I want to bring my best thanks to Mrs. and Mr. Gepp for 
valuable information as to the Avrainvilleas, received not only 
personally during a visit to London last autumn but also by letter 
later on. 
I am also highly indebted to Dr. Ed. Bornet in Paris, who 
has most kindly sent to me original specimens of Crouan’s Herb. 
to be found in Herb. Thuret. 
The Genus Avrainvillea was founded by Decaisne on a speci- 
men from Iles des Saintes, near Guadeloupe in his paper: ‘Sur les 
Corallines ou Polypiers calciféres’ (Annales des sciences naturelles, 
Botanique, II. sér., tome 18, 1842, p. 108). He describes here the 
species Avrainvillea nigricans.
